        field.
         (_Jv_InterpMethod::rewrite_insn_mutex): New mutex.
        (_Jv_InterpFrame:: _Jv_InterpFrame): Pass frame_type.

        (ThreadCountAdjuster): New class.
        (_Jv_InterpMethod::thread_count): New field.
        (_Jv_InitInterpreter): Initialize rewrite_insn_mutex.
        Increment and decrement thread_count field in methods.
